Abstract

Mortality and health care costs associated with hospital-acquired pressure ulcers (HAPUs) increase yearly. After four hours of surgery, the risk of developing a pressure ulcer increases by 33% for every 30 minutes of surgery. Prolonged immobility, lower blood pressures, and increased surface interface pressure may hinder the blood supply delivered to the skin, eventually leading to pressure ulcers. We measured and compared four different OR surfaces to identify the most effective pressure redistribution surface for prolonged OR procedures. The best surface attributes that provide efficient pressure redistribution should have the following properties: the lowest average interface pressure, the lowest peak interface pressure, and the highest skin contact area. Although all surfaces had similar average interface pressures, the air-inflated static seat cushion had the best pressure redistribution properties in the sacral region compared with the other surfaces tested.
